Reflections on Research and Development in the United States Air Force was intended to be part of the now-defunct Warrior Series. While the necessity for that particular series has lapsed, its long-term goal remains valid-to produce books which will appeal to all levels of Air Force people, who may learn from the past and perhaps apply the experiences of past generations to the present. This publication should interest readers who have scant familiarity with research and development, as well as those intimately familiar with the subject. The former will gain an understanding of the outline history of Air Force research and development, while the latter will obtain fresh, personal perspectives. In 1982 General Lew Allen, Jr. called for "the continuing study of military history, combat leadership, the principles of war, and particularly, the applications of air power." All of us in the Air Force community can benefit from such study and reflection. The challenges of today and the future demand no less.
